Cadge (6)
I believe the answer is:
sponge
'cadge' is the definition.
(I know that cadge can be written as sponge)
This is all the clue.
(Other definitions for sponge that I've seen before include "Cadge - porous object used for washing" , "something to eat" , "Porous substance to soak up" , "Heavy drinker" , "soap?" .)
